Answer: ) Khi nào một vật được coi là chuyển động ? Cho ví dụ ?
b) Khi nào một vật coi là đứng yên? Cho ví dụ ?
c) Theo em câu phát biểu “ Khi khoảng cách từ vật đến vật mốc không thay đổi theo thời gian thì vật đứng yên so với vật mốc”. Có luôn đúng không, vì sao?
Explanation:
Answer:
1b. It is called law of the inertia because it overcomes intertia
1c. Why I feel pressed is because of the acceleration trying to overcome inertia .
2a.The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
2b. If the force were doubled, you double The mass it's acting on.
2c. A car with large mass will use more fuel because it needs more energy to overcome the inertia force.
Explanation:
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless being acted upon by an external force.
If anyone can help me that would be nice it’s one question about The Kohlberg Dilemmas.
Two non-metals form a covalent bond.
The answer is oxygen and oxygen.
Answer:
Explanation:
Those kind of problems of electric physics is about capacitors, so the normal questions are:
What are the charge on each electrode?
Solve this you can get other information required in the problem or write down the other questions you need
Capacitance
The charge is find by the equation
